Certain Pella® windows can halt speeding baseballs and others can weather hurricane-force winds. How?
When it comes to hurricane-resistance, Pella HurricaneShield® windows and patio doors rated to ASTM E1996 missile D rating are meticulously tested for impact resistance.
Tests consist of blasting a two-by-four at the window to ensure glass keeps intact. We use our hurricane cannon to propel the wood, which covers 50 feet per second.
It Started with Hurricane Testing
We figured, if we could create a hurricane window with impact-resistant glass, surely we could find a resolution that could halt home runs from Major League Baseball teams.
When Pella was contacted to help outfit a historic building outside of Wrigley Field with home run-resistant windows, that’s precisely what we did.
We overhauled our hurricane cannon to test the home run-resistant windows. We shot baseballs from the cannon at an angle and speed that would recreate the force of a home run.
Our tempered glass resisted the home runs best because it’s tougher and safer than generally used annealed glass.
All About Physics
It requires a speed surpassing 100 mph and a height of more than 100 feet to shoot a baseball out of the park.
In Wrigley’s scenario, we found the baseballs would be traveling at about 60 mph upon striking windows.
But we did more than what was expected and checked impact resistance up to 100 mph.
More Benefits of Tempered Glass in Pella® Windows
Even if you’re not concerned about an MLB home run hurling at your residence, there are many reasons to use strong, tempered glass in your Pella windows and doors.
It’s good for homeowners who want an additional level of safety from their windows or patio doors. Or those who are raising the next great baseball player.
Consider the advantages and highlights of Pella tempered glass options:
- Toughened glass much like what is used in car windows.
- Used where injuries from broken glass are a concern.
- Normally fragments into small, square fragments instead of sharp shards if broken.
- Glass doesn’t come apart if shattered.
Tempered glass is available in all Pella windows and patio doors. To learn more about impact windows and if they may be right for your home, call Pella of Colorado Springs at (888) 883-8364. Or, request a free, in-home consultation online.
